Ambient Ozone Patterns and Ozone Injury Risk to Ponderosa and Jeffery Pines in the Sierra Nevada

摘要

Spatially explicit estimates of ambient ozone exposure to the Sierra Nevada were developed using data from an extensive survey of passive ozone monitors. The study area included the Sierra Nevada subregion, and extended from the Sequoia National Forest in the south through the Lassen National Forest in the north. Both Westside and Eastside forests were included in the ambient ozone survey. This survey provided data at a total of 94 locations across the Sierra Nevada, of which nine were collocated with active ozone monitors. In addition digital elevation maps, and spatial maps of temperatures and precipitation were developed as part of the analysis.
